to work around improper handling of getting paged out. * console/display.c (user_create): Call vm_wire() on the created user data.

libpager: provide 'pager_create_alloc'

2016-08-07T21:28:45Z

Add a variant to 'pager_create' that allocates memory for the user hook next to the pager data increasing locality. * console/pager.c (pager_clear_user_data): Fix type of 'idx', do not free 'upi'. (user_pager_create): Use the new function. * doc/hurd.texi: Document new function. * ext2fs/pager.c (pager_clear_user_data): Don't free 'upi'. (diskfs_get_filemap): Use the new function. * fatfs/pager.c (pager_clear_user_data): Don't free 'upi'. (diskfs_get_filemap): Use the new function. * isofs/pager.c (pager_clear_user_data): Don't free 'upi'. (diskfs_get_filemap): Use the new function. * libpager/pager-create.c (_pager_create): New generic allocation function. (pager_create): Use the new generic function. (pager_create_alloc): New function. * libpager/pager.h (pager_create_alloc): New prototype.

netfs: Remove global reference count lock.

2016-03-21T18:45:11Z

* libnetfs/drop-node.c: Remove use of netfs_node_refcnt_lock. * libnetfs/init-init.c: Remove netfs_node_refcnt_lock. * libnetfs/make-node.c: Initialize refcounts in refcounts_init. * libnetfs/netfs.h: Use refcounts_t for tracking node references. Remove netfs_node_refcnt_lock. Add netfs_nref_light, netfs_nrele_light and handler netfs_try_dropping_softrefs. Adjust comments. * libnetfs/nput.c: Use refcounts_t. Call netfs_try_dropping_softrefs to remove any soft reference that the translator might have acquired during the lifetime of the node. Implement empty netfs_try_dropping_softrefs. * libnetfs/nref.c: Implement netfs_nref_light. * libnetfs/nrele.c: Use refcounts_t and netfs_try_dropping_softrefs. Implement netfs_nrele_light. * ftpfs/dir.c: Use netfs_nref without locking the old netfs_node_refcnt_lock. * ftpfs/node.c: Likewise. * usermux/mux.c: Use netfs_nref to increase hard references of the node. * hostmux/mux.c: Use netfs_nref to increase hard references of the node. * trans/fakeroot.c (new_node): Use a light reference when storing a node in the hash table. * trans/fakeroot.c (netfs_try_dropping_softrefs): Implement netfs_try_dropping_softrefs to remove the node from the hash table. * trans/fakeroot.c (netfs_node_norefs): Remove code to remove the node from the hash table. * trans/fakeroot.c (netfs_S_dir_lookup): Simplify lookup code since we don't need to lock netfs_node_refcnt_lock anymore. * procfs/netfs.c: Remove use of netfs_node_refcnt_lock. * nfs/cache.c: Add mutex to handle exclusive access to nodehash. This replaces the use of netfs_node_refcnt_lock. * nfs/cache.c (lookup_handle): Use nodehash_ihash_lock when accessing nodehash. Use netfs_nref_light to add one soft reference to the node just added to nodehash. * nfs/cache.c (netfs_node_norefs): Use netfs_nref. Don't use netfs_node_refcnt_lock and don't remove the node from nodehash here. * nfs/cache.c (netfs_try_dropping_softrefs): Drop the light reference when the node has no more hard references. * nfs/cache.c (recache_handle): Use nodehash_ihash_lock instead. * nfs/ops.c (netds_attempt_unlink): Use refcounts_references. * console/console.c (netfs_node_norefs): Use a soft reference to store a node in dir_node, cons_node, disp_node, inp_node. * console/console.c (netfs_try_dropping_softrefs): When dropping all soft references remove node pointer from the fields above.

Drop OTHERLIBS and use LDLIBS exclusively

2015-12-31T20:47:32Z

When cross-compiling, OTHERLIBS magically turns -lpthread into the path to the host libpthread.so file, resulting in build issues. LDLIBS does not suffer from this problem and it seems that is already being used in other Makefiles. This patch removes OTHERLIBS entirely from the build system. * Makeconf: Remove references to OTHERLIBS * auth/Makefile: Replace OTHERLIBS with LDLIBS. * boot/Makefile: Likewise. * console/Makefile: Likewise. * exec/Makefile: Likewise. * ext2fs/Makefile: Likewise. * fatfs/Makefile: Likewise. * ftpfs/Makefile: Likewise. * hostmux/Makefile: Likewise. * isofs/Makefile: Likewise. * libhurd-slab/Makefile: Likewise. * nfs/Makefile: Likewise. * nfsd/Makefile: Likewise. * pfinet/Makefile: Likewise. * proc/Makefile: Likewise. * procfs/Makefile: Likewise. * random/Makefile: Likewise. * storeio/Makefile: Likewise. * term/Makefile: Likewise. * tmpfs/Makefile: Likewise. * usermux/Makefile: Likewise.

Remove unused variables

2015-11-06T09:39:53Z

* console/pager.c (user_pager_init): Remove unused variables. * ext2fs/pager.c (create_disk_pager): Likewise. * fatfs/pager.c (create_fat_pager): Likewise. * storeio/pager.c (init_dev_paging): Likewise.

Add support for ANSI.SYS SCP/RCP escape codes

2015-09-12T10:00:48Z

This adds support for CSI s and u, which are equivalent to ESC 7 and 8, saving/restoring the cursor position. * console/display.c (handle_esc_bracket): Added support for CSI s and u.

Fix race condition in ext2fs when remounting

2015-09-06T19:40:20Z

On some systems, ext2fs.static would regularly hang at startup, as a race condition meant it would process paging requests while remounting. To fix this, libpager has been altered to allow inhibiting and resuming its worker threads, and ext2fs uses this to inhibit paging while remounting. * console/pager.c (pager_requests): New variable. (user_pager_init): Updated call to pager_start_workers to use new pager_requests variable. * daemons/runsystem.sh: Removed artificial delay working around the race condition. * ext2fs/ext2fs.c (diskfs_reload_global_state): Call new inhibit_ext2_pager and resume_ext2_pager functions, and leave sblock as non-NULL so it will be munmapped. * ext2fs/ext2fs.h (inhibit_ext2_pager,resume_ext2_pager): New functions. * ext2fs/pager.c (file_pager_requests): New variable. (create_disk_pager): Updated call to pager_start_workers to use new file_pager_requests variable. (inhibit_ext2_pager,resume_ext2_pager): New functions. * fatfs/fatfs.h (inhibit_fat_pager,resume_fat_pager): New functions. * fatfs/pager.c (file_pager_requests): New variable. (create_fat_pager): Updated call to pager_start_workers to use new file_pager_requests variable. (inhibit_fat_pager,resume_fat_pager): New functions. * libdiskfs/disk-pager.c (diskfs_disk_pager_requests): New variable. (diskfs_start_disk_pager): Updated call to pager_start_workers to use new diskfs_disk_pager_requests variable. * libdiskfs/diskfs-pager.h (diskfs_disk_pager_requests): New variable. * libpager/demuxer.c (struct pager_requests): Renamed struct requests to struct pager_requests. Replaced queue with queue_in and queue_out pointers. Added inhibit_wakeup field. (pager_demuxer): Updated to use new queue_in/queue_out pointers. Only wake up workers if not inhibited. (worker_func): Updated to use new queue_in/queue_out pointers. Final worker thread to sleep notifies the inhibit_wakeup condition variable. (pager_start_workers): Added out parameter for the requests instance. Allocate heap space shared by both queues. Initialise new inhibit_wakeup condition. (pager_inhibit_workers,pager_resume_workers): New functions. * libpager/pager.h (struct pager_requests): Public forward definition. (pager_start_workers): Added out parameter for the requests instance. (pager_inhibit_workers,pager_resume_workers): New functions. * libpager/queue.h (queue_empty): New function. * storeio/pager.c (pager_requests): New variable. (init_dev_paging): Updated call to pager_start_workers to use new pager_requests variable.

console: fix error and notification port handling

2015-01-20T19:30:29Z

This fixes a deallocation of an invalid port notably seen on system shutdown. * console/display.c (free_modreqs): Handle errors of `mach_port_request_notification' and check whether the old notification port was valid. (do_mach_notify_msg_accepted): Likewise. (display_notice_filechange): Likewise.
